Texas Instruments SN74BCT2423A & SN74BCT2424A 16‑Bit Latch Multiplexer/Demultiplexer Datasheet
The SN74BCT2423A and SN74BCT2424A are general‑purpose 16‑bit bidirectional transceivers with data‑storage latches and byte‑control circuitry. They are suited for multiplexing or demultiplexing address and data lines in microprocessor‑bus and memory‑interleave applications, offering both inverted and non‑inverted data paths.
Each device provides three 16‑bit I/O ports (A15‑A0, B15‑B0, AB15‑AB0) and a set of active‑low control inputs (ALE, BLE, ABENL, ABENM, etc.) that manage bus transceiver functions, latch transparency, and byte‑enable selection. The handbook includes pin descriptions, logic symbols, functional tables, and a typical memory‑interleave application circuit.

Questions answered in these manuals
What temperature range can the SN74BCT2423A and SN74BCT2424A operate in?
They are specified for operation from 0 °C up to 70 °C.
From: Texas Instruments SN74BCT2423A & SN74BCT2424A 16‑Bit Latch Multiplexer/Demultiplexer Datasheet
How does the ALE input affect the latch behavior?
When ALE is low the latch is transparent; when ALE goes high the data present at the inputs is latched.
From: Texas Instruments SN74BCT2423A & SN74BCT2424A 16‑Bit Latch Multiplexer/Demultiplexer Datasheet
How does the A/BSEL control line work?
When A/BSEL is low, the A15‑A0 bus is connected to the AB outputs; when high, the B15‑B0 bus is connected to the AB outputs.
What are the latch enable inputs and their functions?
ALE, BLE, ABLEA, and ABLEB are active‑low inputs that control data storage; low makes the latch transparent, high latches the data.
